Synthesizing method for 3-methoxyacrylate

The present invention relates to a synthesizing method for 3-methoxy-3-ethoxy methyl propionate, and belongs to the field of chemistry. The synthesizing step comprises the following steps: introducing methyl vinyl ether into trichloroacetyl chloride, and insulating until a reaction is completed; combining BJ01 with anhydrous methanol, adding an acid-binding agent I, and insulating until a reaction is completed; and mixing BJ02 with an organic solvent 2, adding a catalyst, and insulating until a reaction is completed to obtain the 3-methoxyacrylate. The synthesizing method for the 3-methoxyacrylate has the advantages of few reaction steps, easiness in operation, less waste gas, waste water and waste residues, high yield, high purity of products, and inexpensive and easily available raw materials. All the steps have no harsh conditions and are simple in operation and environmentally-friendly, and the solvent are easily recycled and reused, so that the synthesizing method is suitable for industrial production.
